I could have been a bit more clear here: modulo any response you have to
my latest round of comments, I'm mostly happy to let this proceed to
next. So I was thinking you'd have one more re-roll dealing with the
patch 1 problems plus anything else you think worth addressing from my
batch of comments, and then that result would probably be ready for
'next'.

I may have dug my own grave here. ;) I'm actually not incredibly
interested in the overall topic. So I wasn't saying so much "I'll
reserve judgement on simple-ipc until I see callers" so much as "I
expect you'll find any shortcomings in its design yourself as you build
on top of it".
And by "not interested" I don't mean that I think the topic is without
value. Far from it; I think this is an important area to be working in.
But it's complex and time-consuming to review. So I was hoping somebody
with more expertise and interest in the problem space would do that part
of the review, and I could continue to focus on other stuff. That may be
wishful thinking, though. :)
